SCRAPER'FOR GRADING AND DITCHING.

SPECIFICATION formingpart of Letters Patent No. 247,941, dated October 4, 1881.

Application filed March 24, 1881. (No model.)

To all whom it may concern:

Beit known that I, JAMES C. MCINTOSH, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Scrapers for Grading and Ditchin g; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain improvements in that class of earth-Scrapers used for grading and leveling oft' lands and for ditching purposes; and it consists in the combination and arrangement `of certain parts, as hereinafter explained, and pointed outin the claims.

'Referring to the accompanying drawings, Figure 1 is a perspective back view of myscraper, showing head-board A,with side boards, a, and draft-chains D, plates B, with slots cand pin e, and foot-board C. Fig. 2 is a detached view of foot-board C, with pin c. Fig. 3 is a detached view of a slotted plate, B, showing a slot, o.

The foot-hoard C is attached to the plates B by the pin c, passing through the head of footboard G and the slots cof plates B, so that by the independent vertical movement allowed by the slots c the scrapers front surface can be adjusted to any desired slope. In light, sandy soils the scrapers front surface can he dragged square against the dirt, while in stiffer lands the resistance of the earth is overcome by giving the front surface of the scraper any desired slope. While the scraper is in operation it is required to simply tighten the nut on the end 4o of the pin e in order to hold the foot-board C firmly at, any required position. It is usual, also, for the driver to rest one foot upon the foot-hoard C while the team is in motion and the work of scraping going on, the drivers weightovercoming the tendency of the scrapen to turn over and dump its contents until desired. The said foot-hoard C, also, when rigidly attached, as hereinbefore shown, answers the purpose of a handle to guide the scraper and to elevate or depress it in any` manner, as desired.

The draft-chains D serve as a simple and inexpensive device for the team to pull by.

The head-board A is provided with simple and convenient side boards, a, completing or forming the body of the scraper.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A grading and ditching scraper composed of the head-board A, provided with draftchains D and side boards, a, plates B, provided with slots c and pin e, and foot-board C, all combined and operating as set forth.

2. The slotted plates B, attached to the back surface of the head-board A, and serving to connect the foot-board C thereto by aid ofthe pin e, so that the foot-board C may be vertically adjusted, and thus permit of the use of the scraper at any desired slope, all as herein described and set forth.

In testimony whereof I affix my signature
